Referring more particuiarly to the (i1-avv-` 1 gs, the letter .[1designates, generally, a, :Jwudard chassis such as that of the iiord i'he, this chassis irivoiving all the usuai l'ts and heine of the wormdriven type. iv ist oit the details are immaterial. and need il, hespeciiicch it being suiiicient to point thatthe drive shaft i3 isequipped With a uoriii-ii1eshiiig with a Worm Awheel C pro- "f tor thepurpose of drivingI the rear carrying the rear Wheels. It is "vvei knownthat the worm and Worm Wheel enclosed within Va housing D and thatsuitable roller hearings lil are provided at ai'ipiffpriate points 'forreducing triatlon. also Well hiuovvh that the rear wheels are eduipiedwith brake mechanism includank arms 'if with which are connected ods Gextending 'forwardly and conf with the usuel pedal mechanism.

out the invention, l provide uur mmortaat object is the provision ot.trame hars l@ which have outwardly oset orivard ends ll extending outpast a poi"- tiou of the .traine tl of the chassis A. and

vloolted thereto as indicated at l2 eo as to constitute a prolongationof the main trame li also make use oiA au entire rear end constructionA13 such as torres part of the ordinary chassis 'aiuti which is ideuticaitherewith inasmuch as,s it imciudes a, drive "shaft housing M, a rearaide housing l5, Cradius rods 16 and the other ordinary parte. At theforward end of the drive shaft hous-4 ing 14 is a universal oiiithousing l? within which is located the usual universal joint 18 carriedby the forward end of the drive shaft. lt is immateial Whether the driveshaft have the ordinaipinion and ring gear connection with te rearspindles or whether it have a Worm drive connection therewith althoughas a. matter of fact the latter is probably preferable inasmuch aa itconforms to the structure forming; part oi tl'ieo'i'idinary equipment.lChe-uhiversai joint T18 includes a socket or female member 19 as ieusual. lncideutaily, it is ot course apparent that the rear axle of theltrailer attachment is equipped with Wheels 19 with which is associatedthe usuai brake mechanism ideiiticaliy the same as that provided oie theWheels ot the .maia chassis and o operated hy means of crank arms 20.

ln itietailiiig the attachment, it is iiecessary that the usuai Wormprovided for driving theiivorm 4wheel t) he replaced hy' a Worm 2i.which has its end terminating in an extension 22 et a-Lfiguiar formationfitting Within the socket aad completing the universal` joint structureor: connection.

Use is also made of a .housing member 23 which is bolted onto theoutstaudihgiiauga 9 l of thehousing and to the outstanding Harige ot thehousing section i7 for the uuiversal joint. When theee connections areproperly made, it is quite obvious that the drive shaft iu the trailereectiou will he operatively connected with' the drive shaft l5 in themain chassis so as to operate in unison therewith so that the Wheels ofthe trailer attachment 'iviil he positively driven in exactly the samemanner and at the same speed as the wheels oi the main chassis.

In order that the brake mechanism lfor the wheels ot the attachment `mayhe operated in unison 'with the hi'alce mechanism for the Wheels of themain chassis7 li provide reech rooie or other' connecting ineens A con--@het l iurvel thus provided e, very simplyeonstructed und eerilyinstalled attachment by means of which an lordinary four wheel ,chassismay he converied into one of the six Wheel types, s perticulnr featureof adven-I tage beinggthai; use is made of standard addi, tional partewhich may he oonnected with or installed in conjunction with the regularequipment with the addition of va. ver few entre vparte replacing piertof the or inary equipment. it is believed that the construetion,operation and advsntaffes will be read ily eppnrent to one skilied inthe art Without further explanation.

While 1 here shown and described the preferred embodiment of theinvention, I

desire to .have it understood that l reserve' the right to make suchchanges in the form, construction und arrangernt #if parte as will :notdepart from the smit o; the invern tion or the' scope of thesuqiijoinedclaims',

Hoving thus described the invention, I` oluimzl. ln combinstionlwithevehicle chassis including e frame, a rear axle housing carried thereby,rear wheels, radius rods connected with the ends of the axle housing andn drive shaft housing connected with the rear axle housing, a Worm`wheel for driving the rear Wheel, e drive shaft within the drive shafthousing carrying a, Worm meshing' with the Worin wheel; a trailerottave-'hment comprising n freine including longitudinel bers havinglaterally oset portions to ele-:ar the rear cross ber of the first namedframe, the frame of me trailer being rigidly secured to the frame of thechassis, a rear' ture of the chassis, e drive sha-it i'or the at itaohment, and e universel infini: connection 1 between said last nameddrive shaft o o, the Worm oi the chassis for commnmoeting `movement tothe wheels of the attachment.
